Catalytic Converter
This ATV is equipped with a three way catalytic converter. The
catalytic converter contains precious metals that serve as catalysts,
promoting chemical reactions to convert the exhaust gasses without
affecting the metals.
The catalytic converter acts on HC, CO, and NOx. A replacement unit
must be an original Honda part or its equivalent.
The catalytic converter must operate at a high temperature for the
chemical reactions to take place. It can set fire to any combustible
materials that come near it. Park your ATV away from high grasses,
dry leaves, or other flammables.
A defective catalytic converter contributes to air pollution, and can
impair your engine’s performance. Follow these guidelines to protect
your ATV’s catalytic converter.
• Always use unleaded gasoline. Even a small amount of leaded
gasoline can contaminate the catalyst metals, making the
catalytic converter ineffective.
• Keep the engine in good running condition. A poorly running
engine can cause the catalytic converter to overheat causing
damage to the converter or the ATV.
• If your engine is misfiring, backfiring, stalling, or otherwise not
running properly, stop driving and turn off the engine.
Have your ATV serviced as soon as possible.
